Pro-tip: if your mouse and or keyboard aren't suiting your ergonomic needs, go to your local auto parts store and buy a tube of JB putty or Quiksteel epoxy putty.
This stuff kneads into a modeling clay like substance that then hardens up like a motherfucker in 5 minutes.
I got sick of my mouse giving me crab-hand, so I bulked up all the buttons and gave them distinct textures and curves.
